By THOMAS E. WESSEL REMINGTON MODEL 40X TARGET RIFLE The Remington Model 40X small bore target rifle was introduced in 1955. Chambered for the cal. .22 long r i fl e c a r t r i d g e , t h e M o d e l 4 0 X i s o f single-shot type with speed-lock firing mechanism. The bolt has 2 large locking lugs. The upper lug engages the forward edge of the receiver bridge, whereas the lower lug is housed in a mortise c u t i n t o t h e b o t t o m o f t h e r e c e i v e r . The trigger mechanism is adjustable for weight of pull, travel of trigger, and overtravel of trigger. Adjustment for weight of pull is made by loosening or tightening an external screw that is located within the trigger guard loop. The barreled action must be removed from the stock assembly to make the o t h e r t r i g g e r a d j u s t m e n t s . A m o u n t o f trigger travel is varied by adjustment of the trigger stop screw in rear of the trigger assembly. To make this adjust ment, screw in trigger stop screw until firing pin will fall without trigger being pulled. Then back off trigger stop screw approximately Va turn, or until firing pin will not fall unless trigger is pulled. E n g a g e m e n t o f s e a r w i t h c o n n e c t o r should be approximately .010". An in spection hole in right side of trigger housing is provided for viewing this engagement. Adjustment for trigger overtravel (overdraw) is made with the trigger stop screw at front of trigger housing assembly. To make this adjustment, screw in trigger stop screw until firing pin will not fall while pulling trigger. Continue pulling trigger and screw out trigger stop screw until firing pin will fall. Then screw out trigger stop screw a fraction more. A drop of Du Pont or a similar cement should then be placed on heads of both trigger stop screws to seal the adjustments.
